The risk is defined by the bullion tips providers as the deviation of actual returns from expected return. Hence measurement of risk needs data for actual as well as expected returns.

The likelihood of occurrence, or probability estimate for each return value.   However, in real life, we may not be able to estimate future returns, or even correctly decide the range of values that returns could take.

Since most investors tend to form expectations on the basis of historical performance of an asset, it is a common practice to represent expected returns by an average return. For example, suppose the annual return from e
